+# --description--
+
+When we start using jQuery, we will modify HTML elements without needing to actually change them in HTML.
+
+Let's make sure that everyone knows they shouldn't actually modify any of this code directly.
+
+Remember that you can start a comment with `<!--` and end a comment with `-->`
+
+Add a comment at the top of your HTML that says `Code below this line should not be changed`
+
+# --hints--
+
+You should start a comment with `<!--` at the top of your HTML.
+
+```js
+assert(code.match(/^\s*<!--/));
+```
+
+Your comment should have the text `Code below this line should not be changed`.
+
+```js
+assert(code.match(/<!--(?!(>|->|.*-->.*this line))\s*.*this line.*\s*-->/gi));
+```
+
+You should close your comment with `-->`.
+
+```js
+assert(code.match(/-->.*\n+.+/g));
+```
+
+You should have the same number of comment openers and closers.
+
+```js
+assert(code.match(/<!--/g).length === code.match(/-->/g).length);
+```
